Does the LC require a PRAM battery to start?

No, the oiginal LC will start without one, as does the LC II and LC III/LC III+ and the Performa equivalents of them.

@joshc & @MrFahrenheit Thanks for your quick replies. I think that you are right about the LC475. The PRAM battery needs to have a sufficient charge for the video output to work but isn't actually necessary to start the machine up.

There is varying experience on LC models and requiring a PRAM battery.

My own anecdotal evidence is that when there is a red push button reset for the PRAM on the board, it definitely requires a battery (without resorting to trickery of on/off cycles).

I have seen all models of LC-Lc475 with the red button, and I’ve seen LC, LC2 without.

Interesting. I don't have an LC II anymore to try it out but I am pretty sure the couple I had worked fine without one.
